Denial Of Service Attacks

From Computing and Software Wiki

A denial of service attack (DoS attack) is generally the attempt to degrade the resources of another computer, or crash it, so the that the intended users of that computer can not longer use it. The methods used to do such an attack usually involve an attempt to exploit a weakness in one of the protocols that are used on the internet to cause harm to the target machine or make it lose and use resources at an unusual level. Since denial of service attacks are so common today protection has become a very important concern for machines on the internet.
